BAScript
Scripting engine for Pascal compilers.
BAScript is a simple scripting engine written in Object Pascal you can use to add scripting to your Delphi, Lazarus or Free Pascal applications ("host program") to extend their functionality without the need of recompiling them. The virtual machine defines its own language, called the BAScript language. It is a low-level language, somewhat similar to the Assembler language, which is not intended to be easy to program but easy to execute. So it is recommendable to use other higher level languages and translate them into BAScript language. Package includes two compilers that translates from a higher-level language to the BAScript language. You should note that BAScript is intended to be lightweight, so it has not mechanisms to handle complex data structures or large amounts of data or code. On the other hand, it has less need for memory and resources than other scripting interpreters. If you need more power you may try PascalScript. -

QToaster
A simple and fast frontend for the QEMU Emulator - Freeware.
QToaster is a simple app that executes QEMU with proper command line parameters (a frontend). The features are pretty basic, the executable is small and is a portable application. I needed something to automate QEMU quickly operate fast without having to worry about setting things up. I just wanted to get moving fast. It is designed just for that. It will keep your last machine settings and reload them from the .ini files that it creates. The main purpose I needed this for is Android - using Limbo. If something works on QEMU then it has a good chance of working on Android. You don't need to put QEMU in your environment path, just point to its base folder. It doesn't need any special runtimes (java, .net, Python, etc.), it only needs the utility file Lutil.dll. Frontend was made for: http://69.170.215.148/nothoro/software/QTPage/QToaster.html QEMU emulator version 6.0.0-rc2 available at: https://qemu.weilnetz.de/w64/2021/ When you run the installer, it will extract to a subfld -
